TOOL-HOLDER..

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed April 22, 1909. Serial No. 491,479.

To att whom t may concern:

Be it known that I, CHRISTIAN GRUNDER, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inTool-Holders, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to stamp and punch holders, and more particularlyto certain improvements of the holder forming the subject mattei' of myPatent No. 796,324, granted August l, 1905.

The present invention aims to provide a more durable and efficientholder which will facilitate a Workman in accurately7 using the same;the principal object of the present invention being to support theholder above the piece of work to be stamped or punched, whereby theworkman can observe the die ends of the stamps or punches, and determinewhether the same are correctly positioned relative to the piece of work.

Besides the improvement cited above, I have made certain otherimprovements in the details of construction, all of which willhereinafter appear as the improvement is more fully described andclaimed, and reference will now be had to the drawing accompanying thisapplication, wherein there are illustrated the preferred embodiments oflny invention, but it is to be understood that the structural detailsthereof can be varied or changed without departing from the spirit andscope of the invention.

In the drawings, Figure 1 is a plan of the stamp or punch holder partlybroken away and partly in horizontal section, Fig. 2 is a side elevationof the same partly broken away and partly in vertical section, Fig. 3 isa side elevation of a portion of the holder partly broken away,illustrating the opposite side from that shown in Fig. 2, Fig. 4L is across sectional view of the holder taken on the line X-X of Fig. 2, Fig.5 is a perspective view of one end of the modified form of holdersupport, and Fig. 6 is a perspective view of a portion of the body ofthe holder, illustrating the same in an inclined position to clearlyshow the position of said holder.

Referring to the drawings in detail a holder in accordance with thisinvention comprises a body portion consisting of an angle plate,preferably of metal, embodying a vertically extending flange l and ahori- Zontally extending flange 2. Formed integral with the inner faceof the flange l and of a length equal to the height of said flange arevertically disposed partitions 3 which at their tops are formed integralwith the inner face of the flange 2. The partitions 3 are spacedequidistant so as to provide a series of compartments for the receptionof grips to be hereinafter referred to. The partitions 3 are interposedintermediate the ends of the fiange 1. The horizontal flange 2 adjacentto the flange l is reinforced as at 4 and the said reinforced portion Ais provided with a series of longitudinally disposed openings which openinto the top of the compartments formed by the partitions 3.

The body portion is mounted upon a support 8, the latter being formedwith depending ends 9 constituting legs and which maintains the bodyportion some distance above the work which is to be operated on. Thesupport 8 is formed with a series of longitudinally disposed openingsl() with which the bottoms of the compartments formed by the partitions3 communicate or in other words, the openings compartments and openings10 are in vertical alinement with respect to each other. The support 8is of greater length than the body portion and mounted upon said supportS and extending in the body portion so as to be positioned below theflange 2 and against the flange 1 is a bar ll, preferably of wood, whichconstitutes what may be termed a handle support. The handle comprises aframe la which is formed at its bottom with inturned flanges restingupon the bar 11 and the flange 2 and has connected to its top bySuitable hold fast devices a grip bar 15 preferably of wood. The support8 at one end thereof is coupled or connected to the flange Q by a bolt Gand a nut 7 and the support 8 intermediate its ends is connected to theflange 2 by another bolt 6 and a nut 7 this last mentioned bolt 6extends through the bar l1 and also one of the inturned Hang-es of thehandle frame 14. The support S at its other end is connected to the bar1l by a bolt l2 and a nut 13. The bolt l2 also extends through theinturned flange of the handle frame 14:. Owing to the disposition of thebolts in the manner as stated the body portion, bar l1, support 8 andhandle frame 1A are coupled together.

The bar 11 is of less width than the width of the iiange 2 and thesupport 8 is of less f width than the Iiange but of greater' width thanthe bar 11 and mounted upon the support S and against the free edges ofthe partitions 3 is a plate 16 which corresponds in length to thesupport 8. The plate 16 is of a height as to extend to the inner .faceof the flange 2 and the upper edge of said plate 16 is cut away at aplurality of points as at 17 to provide seats for a function to behereinafter referred to. The said plate 16 in proximity to the cut awayport-ion 17 is furthermore provided with a plurality of longitudinallydisposed openings 1S which register with the compartments formed by thepartitions 3.

Arranged in each of the partitions 3 are a plurality of gripping members19, each of which has a hook shaped upper end 2O adapted to be mountedupon a seat formed by the cut away portion 17 whereby the said grippingmembers are suspended within the compartments, owing to the fact thatthe liook-shaped ends of the said gripping members overlap the seatsformed by the cut away portions 17. The gripping members 1S) aresuspended within the compartments directly in front of the openings 1Sin the plate 16.

Mounted against the outer face of the plate 16 at the top thereof andcorresponding in length to the flange 2 a spring holder 21, the latterbeing provided with a plurality of transversely-extending openings 22which register with the openings 18 and extend at right angles withrespect to the plate 16. Vithin each of the openings 22 is arranged anextensible and contractible coil spring 28. The springs 23 project intothe openings 18 and engage the gripping members 1S) whereby said members1f) are maintained in engagement against the inner face of the flange 1when the said members i are not gripping tools or are maintained inengagement with the tools when the tools are mounted in the compartmentsformed by the partitions 3. The inner face of the holder 21 at the topthereof is provided with a series of cut away portions 24, so as toprovide clearances for the hooked ends 2O of the gripping meii'ibers 19when the said hooked ends 20 are mounted upon the seats formed by thecut away portions 17 at the top of the plate 16.

To maintain the springs 23 in the openings 22 and to furthermoreconstitute an abutment for the outer ends of said springs 23 an anglebar 25 is provided. rlfhe said bar 25 corresponds in length to theholder 21 and the flange 2, and the said bar is so disposed as to engagethe outer and lower faces of the holder 21, and to also abut providedfor securing the plate 16, holder 21 and bar 25 in position and in thisconnection it will be stated that the bolts 26 are right angularlydisposed with respect to the bolt 6 and that the said bolts 26 extendthrough the plate 16, bar 25, holder 21 and flange 1 and project fromthe bar 25 and carry on their projecting ends the nuts 27. To furthermaintain the plate 16 in position a bolt 28 and a nut 29 is provided,the said bolt 28 extending through the 'bar 11 and plate 16. One of thebolts 26 also extends through the bar 11.

The springs which are mounted in the openings 22 are preferablyconstructed of brass while the gripping members are preferably made ofsteel. The constructing of the springs of brass makes them more durableand furthermore the employment of the springs in the manner as statedcauses the gripping members to perform their function in an unusuallysatisfactory way and more efficient manner than that obtained by thegripping members solely as disclosed in my prior patent.

The support 8 as shown in Figs. 2 to 4 inclusive is used in connectionwith flat work, but should the tool holder be used in connection with acylindrical object or an object of other shape than flat, the dependingends of the holder are recessed as at SO, Fig. 3, to receive the pieceof work to be stamped or punched.

The holder as liereinbefore set forth is particularly designed forstamps and punches, but can be used for holding and correctlypositioning the various kinds of tools to be struck by a hammer or otherinstruments for making an impression upon a piece of work.

It is thought that the manner in which the tool holder is used would bereadily understood from the foregoing description taken in connectionwith the accompanying drawings, but it will be stated that the tools,such as stamps and punches, are inserted through the openings 5 into thecoin partments formed by the partitions 3 and maintained in saidcompartments by the gripping members 19 and the action of the springs 23against said members 19 as will be evident.

ln supporting the tool holder above the work in such manner as shown, itallows of the circulation of air between the holder and the work, sothat should the work be hot, any wooden parts of the holder are cooledfrom the circulation of air so as to protect said wooden parts frombeing scorched or burned.
